In the event of an ECDIS failure, what is required of the back-up ECDIS?

• A. Availability and independent power source
• B. Real-time data updating
• C. Larger display screen
• D. Integration with ARPA systems

Answer: (A)

In the event of an ECDIS failure, having a backup ECDIS system that is readily available and equipped with an independent power source is crucial for maintaining navigational safety. This ensures that the vessel can continue to navigate effectively without interruption, even if the primary ECDIS fails. The independent power source is particularly important because it prevents reliance on the main power supply, which may also fail, thereby enabling the backup system to function in critical situations. While real-time data updating, a larger display screen, and integration with ARPA (Automatic Radar Plotting Aid) systems can provide additional benefits and enhance navigational capacity, they are not strictly required for the backup ECDIS to fulfill its primary role. The primary focus should be on ensuring availability and system reliability in emergency scenarios, making these features secondary to the fundamental requirement of having a dedicated and operational backup that can be used without failure.
